Pre-wrapped two-piece ring airfoil projectile of non-hazardous material

摘要: The invention is a non-lethal projectile for use in riot control. structure an improvement over prior similar projectiles, that the sealing of control agent payload enhanced, thereby preventing leakage and consequent rejection. allows complete cavity, before filling, then introduction by hypodermic type needle to penetrate sturdier rubber-like final closure cover which self-seals when withdrawn.
